During the combustion process of 100 L of gasoline, a car releases to the environment, approximately 215 kg of carbon dioxide (CO2). Knowing that one mole is the amount of matter which contains the number of particles equal to Avogadro's constant (6.02x1023 mol-1 ),Determine the number of CO2 molecules that are released during this combustion process.
From a Periodic Table
carbon weighs ~ 12 gm/mole
oxygen weighs ~ 16 gm/mole
so CO2 weighs 44 gm/mole
214 kg = 214 000 gm
214 000 gm / 44gm / mole = 4863.6 moles
4863.6 moles * 6.02 x 1023 particles/mole = 2.928 x 1027 particles of CO2
